Normal behavior for Android is to keep Activities alive for as long as possible so that they can be launched faster. The system will completely remove (that is, destroy) Activities only when the device runs low on memory. By checking this option, you can simulate how your app will behave on a device with much less available memory. You can further simulate this kind of behavior by changing the Background Process Limit option, which forces background operations to stop much earlier.

You can control use of the pm command in a similar way to how you work with the Application Manager. The Package Manager lets you interact with the installed applications (packages), allowing you to list, install, uninstall, and inspect the features and permissions on the device.

For instance, if you want to list all the installed packages (that is, installed apps), you can type the following: $ adb shell pm list packages In addition to the adb commands just covered, there are many others you need to be familiar with.
